Well Hitler and other mass murderers were likely influenced by Darwins theories. The propaganda shows as much.
Though it's not like that makes Darwin responsible or a racist.
Though he probably was a racist. Who wasn't back then. The descent of man seemed to portray him as such... but once again... just about everyone was a racist then.
Regardless it's not like the Holocaust should be held against him. For all we know the Jews could of been scapegoated anyway. Such things aren't unusual. It's just a matter of the science being used as a justification. Like when the french claimed they were superior using that head measuring science. (Though in addition they actually fudged the numbers on it btw.)
It's not like scapegoating one race is something that was new to WW2.
